TO ALL WHOM IT MAY CONCERN:

Be it known that I, E. R. WILLIAMS, of Rochester, in the county ofMonroe, and State of New York, have i invented a. certain newr anduseful Improilement in Fruit-Jars; and I do hereby declare that thefollowing is a full and exuct description thereof, reference being hadvto thel accompainying drawings, making part of this specification, inwhich-+- Figure lis n. section of a. jar with my improved stopper.

Figure 2, n perspective view of the stopper.

Likeletters of reference indicate corresponding parts in beth figures.

My invention consists in the special ferm and arrangement of thestopperywhichis made -grooved on onel side andinelined on the other, andwhich pncksfin the mouth'of the jar by means of an elastic strap, asherev inafter set forth. v

In the accompanying drawings, A indicates the jar, and B the stopper,which is preferably made of glass. On one sideof the stopper is formed ugroove or coucnvity, a, which extends around about one-third of itscircumference, and graduates into an incline, Z1, as shown. The stopperB is provided with the usual packing, d.

On one side of the stopper is formed a lug, g, corresponding in positionwith lug h on the neck of thejar. Over these lugs is hooked an elasticband, z', of India. rubber, which serves to hold the stopper in placewhen it is inserted in the mouthp of the jar, which is doneby firstinserting the'grooved side, and then pressing down the-incline, therebyhooking the stopper in pl'zfce. I

By means of. the groove a of the stopper fitting over the neckp, thestopper itself is made self-retaining "on" one side, while on theopposite side the elastic band hooking over lugs q h, serves to securethe stopper in place. Y

Much difiiculty has been experienced from the pressure of the gas thatcollects from the fruitinside the jar, and sometimes the pressure is sogreat as to force the cover oft altogether, and expose the fruit. In mydevice, when the pressure of the gas'issuiiicient to overeome'theatmospheric pressure outside, thc elasticity of the band z' will yieldenough for the stopper to rise and allow the gas to escape, the groovedside acting as a sort of hinge.l p y i This eonstructionis exceedinglycheap, and the packing und locking in place are accomplished inthesimplest mnnncr. These advantages are obvious at rst glance.

Whait I claim as my invention, and desire to secure by LettersPatcnt,'is

The construction of the Vstoppern, with agroove, a, extending part wayaround, and graduatinginto au Iincline, Z1, when employed in conn'ectionwith the elastic band z', in the manner and for the purpose specified.

Innvitncss whereof, I have hereunto signed my name in the presence oftwo subscribing witnesses.

E. R. WILLIAMS.
